Presented in this book is free technology for making self powered green energy machines. The machines produce electrical energy as well as hydrogen and oxygen gases or brown gas. They are kick-started using a temporary external source of power and after that they power themselves using a small portion of the output energy they produce and the rest of the output energy is used to do work. One use of this technology converts a computer into a self powered machine which is able to generate power to do work while running itself with a small portion of its output power. This book is a call to research for all lovers of green technology. It describes all devices disclosed with schematic diagrams for making it easy to understand and experiment.
